Abstract: A vibroacoustic therapy bed delivers a sensory experience using integrated vibrational transducers, sounds, lighting effects, and/or other sensory elements. The vibroacoustic therapy bed includes a series of interconnected base elements and a pad. The vibroacoustic therapy bed is configurable between a flat configuration in which the base elements support a user laying on the pad and a stowable configuration in which the base elements pivot with respect to each other utilizing hinge connectors to form a compact structure suitable for stowing. The base elements may furthermore include an isolation element for attenuating transfer of vibrational energy from the vibrational transducers to the ground.

Abstract: A method for determining the location of underground cables and pipes is disclosed. In some embodiments, the method includes measuring a set of electromagnetic field magnitudes and phases at a plurality of positions while traversing a target line parallelly using 3D electromagnetic coil sensors, the 3D electromagnetic coil sensors being orthogonally oriented to the target line, modeling a set of expected complex electromagnetic field magnitudes of a single underground conductor at each of the positions to form a set of values corresponding to a set of individual models for the target line, determining which of the set of individuals models is a best model, determining confidence information at each of the positions based on a comparison between the measured set of complex electromagnetic magnitudes and phases and the best model, and determining parameters at each of positions related to the target line from the best model.

Abstract: A bearing system comprises a support member and a rotational element having a generally cylindrical bearing surface, and a plurality of detents defined upon and extending in from the cylindrical bearing surface, and may include means for rotating the rotational element in relation to the support member. The bearing system also comprises at least three bearing assemblies, each comprising a cam member rotatably mounted to the support member. Each of the cam members comprises a cam surface having a profile that contacts the cylindrical bearing surface and rotates away from a home position when the cam is rotatably positioned to meet one of the bearing regions, and does not contact the cylindrical bearing surface when the cam is rotatably positioned to meet one of the detent regions. Each of the cam members are rotationally biased toward their home position.
